LM4041QCEM3-ADJ/NO

Voltage Reference Overview

The LM4041QCEM3-ADJ/NO is a precision micropower shunt voltage reference from Texas Instruments, part of the LM4041xQ series. It features an adjustable output voltage range from 1.225V to 10V using external resistors. The device offers an initial accuracy of 0.5% and a temperature coefficient of 150 ppm/°C. It operates with a minimum current of 45µA (typical) and supports a maximum shunt current of 12mA. Designed for stability with any capacitive load without requiring output capacitors, it functions within an extended temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Voltage Reference Feature Summary

Voltage Reference Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm the package type, temperature grade, and automotive qualification status. Ensure the ordering code matches the required output voltage range and accuracy class. Cross-reference the manufacturer's latest documentation for any pinout or electrical specification updates before finalizing procurement.

Voltage Reference Selection Notes

Select this component when an adjustable shunt reference is required in space-constrained SMD packages like SC-70 or SOT-23. It is suitable for applications demanding low power consumption and high stability across wide temperature variations. Consider the 0.5% accuracy and 150 ppm/°C drift if precise calibration is not feasible. Verify that the load current requirements fall within the 45µA to 12mA operating window.

Voltage Reference Part Context

This part belongs to the LM4041 family of micropower shunt voltage references. The 'Q' designation indicates automotive qualification, while 'CEM3' specifies the SC-70-5 surface-mount package. The 'ADJ' suffix denotes the adjustable output version, allowing designers to set the reference voltage between 1.225V and 10V. This series utilizes laser-trimmed Zener-zap technology for improved accuracy and lower noise compared to standard Zener diodes.
